Citrus History, Taxonomy, Breeding, and Fruit Quality
2019
In May, every year since 1857, in the great park of Sans-Souci in Potsdam just outside Berlin—a park begun in 1745 by Emperor Frederick II of Hohenzollern and expanded a century later by Frederick William IV—the doors of the great Orangerie open in and a Renaissance-style garden called Sizilianischer Garten is set up. On horse-drawn carriages,large olive and citrus trees are brought outdoors, and are then raised in masters. For the young European who, in the second half of the 18th century and in the first decades of the following, traveled to Italy to see and study Renaissance culture and the remains of Greek civilization, the citrus species and fruits and groves of southern Italy became t…

STUDIO DEI MECCANISMI DI MORTE CELLULARI INDOTTI DAL CANNABINOIDE SINTETICO WIN IN CELLULE TUMORALI IN COLTURA
2014
Per lungo tempo, i cannabinoidi sono stati considerati come farmaci lenitivi ma non curativi della patologia cancerosa. Tuttavia, negli scorsi anni, è stata suggerita una potenziale applicazione dei cannabinoidi come droghe antitumorali, anche se il loro meccanismo d’azione non è ancora ben conosciuto. Gli obiettivi di questo studio sono stati: - la valutazione degli effetti del cannabinoide sintetico WIN55,212-2 (WIN) su differenti linee di cellule tumorali in coltura (cellule di carcinoma colorettale HT29 e cellule di osteosarcoma umano MG63) e – la valutazione dei meccanismi molecolari indotti dal trattamento con il cannabinoide. I risultati riportati indicano che in entrambe le linee ce…
UNRAVELLING THE ROLES OF THE NUCLEAR PROTEIN 1 DURING ER-STRESS INDUCTION
2020
Background: NUPR1 was described as a transcriptional factor involved in the regulation of various cellular stress-response genes, playing a crucial role in the condition of the endoplasmic-reticulum (ER) stress, thus emerging as a common molecular factor of different pathologies, obesity, hepatic steatosis, and cancer. In the present work we aim to explore how NUPR1 interacts with some pivotal genes that are the major modulators of the ER stress and metabolic cell functions. In particular we investigated the biochemical and molecular effects arising from the loss of NUPR1 in ER stress physiological conditions. Methods: We used prolonged high fat diet (HFD) feeding to induce ER stress physio…
Do social comparison and coping styles play a role in the development of burnout? Cross-sectional and longitudinal findings
2006
The present longitudinal research among 558 teachers focused on the role of upward comparisons (with others performing better), downward comparisons (with others performing worse), and coping styles in relation to burnout. Assessed were identification (recognizing oneself in the other) and contrast (seeing the other as a competitor) in upward and downward comparison. Cross-sectionally, downward identification and upward contrast were positively related to burnout and negatively related to a direct coping style, whereas upward identification was negatively related to burnout and positively related to a direct coping style. Downward identification was positively related to a palliative coping…
The Professional Stress of Preschool Education Teachers
2018
Zawód nauczyciela można chyba zaliczyć do profesji o dużym ryzyku utraty zdrowia – zarówno w sensie fizycznym (sfera somatyczna), jak i psychicznym. Świadczą o tym statystyki dotyczące oceny zdrowotności dość dużej zbiorowości nauczycieli. Liczne zmiany strukturalne (reformy oświaty) oraz wzrost oczekiwań zawodowych wobec nauczycieli – zwłaszcza wychowania przedszkolnego – spowodowały wyraźne nasilenie doświadczanego przez nauczycieli stresu. Niniejszy artykuł poświęcony jest problemowi stresu w pracy zawodowej nauczyciela wychowania przedszkolnego. Omówiono i wyodrębniono w nim najważniejsze czynniki wywołujące reakcje stresowe, jak również zidentyfikowano presje będące źródłem stresu. Na …
Hybrid equilibrium element with high-order stress fields for accurate elastic dynamic analysis
2021
In the present article the two-dimensional hybrid equilibrium element formulation is initially developed, with quadratic, cubic, and quartic stress fields, for static analysis of compressible and quasi-incompressible elastic solids in the variational framework of the minimum complementary energy principle. Thereafter, the high-order hybrid equilibrium formulation is developed for dynamic analysis of elastic solids in the variational framework of the Toupin principle, which is the complementary form of the Hamilton principle. The Newmark time integration scheme is introduced for discretization of the stress fields in the time domain and dynamic analysis of both the compressible solid and qua…
Effect of drought on sorbitol and sucrose metabolism in sinks and sources of peach
2000
In peach (Prunus persica [L.] Batsch.), sorbitol and sucrose are the two main forms of photosynthetic and translocated carbon and may have different functions depending on the organ of utilization and its developmental stage. The role and interaction of sorbitol and sucrose metabolism was studied in mature leaves (source) and shoot tips (sinks) of'Nemaguard' peach under drought stress. Plants were irrigated daily at rates of 100, 67, and 33% of evapotranspiration (ET). The relative elongation rate (RER) of growing shoots was measured daily. In mature leaves, water potential (ψ w ), osmotic potential (ψ s ), sorbitol-6-phosphate dehydrogenase (S6PDH, EC 1.1.1.200), and sucrose-phosphate synt…
Tributyltin(Iv) butyrate: A novel epigenetic modifier with er stress-and apoptosis-inducing properties in colon cancer cells
2021
Organotin(IV) compounds are a class of non-platinum metallo-conjugates exhibiting antitumor activity. The effects of different organotin types has been related to several mechanisms, including their ability to modify acetylation protein status and to promote apoptosis. Here, we focus on triorganotin(IV) complexes of butyric acid, a well-known HDAC inhibitor with antitumor properties. The conjugated compounds were synthesized and characterised by FTIR spectroscopy, multi-nuclear (1H, 13C and 119Sn) NMR, and mass spectrometry (ESI-MS). In the triorganotin(IV) complexes, an anionic monodentate butyrate ligand was observed, which coordinated the tin atom on a tetra-coordinated, monomeric enviro…
